In November 2025, my 2022 Hyundai Santa Fe began to hesitate when accelerating and would almost "jerk" when I pressed the gas pedal. Soon after my check engine light came on and I made an appt to take it for the closest Hyundai dealership (as it's still under warranty 33k miles) Upon running a check the dealership notified me that Fuel Injector 1 has misfired and will be replaced. I receive my vehicle back and not even 100 miles later my check engine light in on again and the same issues are arising. Back to the dealership to see now Fuel Injector 3 has misfired and there is an open TSB showing all 4 Fuel Injectors need replaced. My vehicle was finally returned to me in January 2026. It is now February 16, 2026 and my check engine light in on YET AGAIN. I've been given the run around from Hyundai Corp about fixing this vehicle. Why is this acceptable treatment when a vehicle is under warranty ?

On [XXX] my car started having trouble accelerating at some times- just happened out of the blue while driving normally. I was almost to my destination, so I parked and when I came back out, there was a message on the car screen that there was a problem with the transmission and to have it evaluated at my convenience. I was near the dealership so I drove there and they were unable to look at the vehicle but I asked if they could at least see what was wrong and if it was OK to drive. They said the code was DTC P1C2D03 and I was probably getting a new transmission. This code also showed up in the app. The TSB for this says that when this code is on the transmission will need to be replaced. [XXX] . They didn't have any appointments for diagnostics until 8/27/24, and told me it was safe to drive. My car continued over those 10 days to hesitate while accelerating at different times while driving. I never knew if I pressed the gas if I would get correct acceleration or not, which makes turning into traffic, merging, etc. unsafe. I also had 1 incident where I was at a stop sign and got no response at all from the gas pedal. I had to turn the car off and back on to get it to go. My car has only 12,000 miles. My car has been at the dealership now for 10 days waiting on them to do the diagnostics. On day 9 they called and said all it needed was a software update of the transmission control unit software and that they performed that update, test drove it twice and it was performing as expected. When I went to pick it up, the person who drove it from the lot into the service bay got out and told me the check engine light was on and there was an error about a transmission issue on the screen. The DTC P1C2D03 code is back on per the My Hyundai app. So they kept the car again and still waiting to find out what they are going to do.

On November 28 2023, I was pulling onto a small highway when an alarm went off, car stopped (engine off) as other cars were coming towards me. The message displayed was "autostop is off. Shift to P or N and start engine manually". Because the alarm was so loud and I was concerned, I snapped a picture which will be attached. I immediately pushed start button and was able to get out of the way. I had not turned the Idle Start Stop (ISS) button to off - so supposedly it was on. (You have to push this button to turn ISS off. This happened twice until I was able to get to service department. After much time (and using a loaner car) Hyundai agreed to provide a new battery because of its health. This happened again. I took the car back and the manager showed me a technical service bulletin - regarding my car - "Rough Shift and Hesitation Improved Logic". This didn't sound like Idle Start Stop bulletin but I was assured it was (attached). Though the stall has not occurred since, the ISS icon at times just isn't there. My dealer is communicating with Hyundai to try to keep my car again and provide a loaner. I am reporting this because many others on Hyundai Forums are describing the same incidents. Yet I haven't seen anyone mention the Technical Service Bulletin, even though many have taken this problem to their dealer. To me this needs to be considered for a recall. I had a daughter and grand daughter in my car and had no idea what to do with cars approaching. Fortunately, just pushing start worked. I have read the manual and know what is required for ISS to work. All requirements were net. It is possible the TSB has fixed stall issue so I am mainly reporting for other drivers.

The issue with Hyundai 2.5 L turbocharged engines is getting a lot of exposure on-line. My story begins about a year ago with me complaining to the Hyundai service department about my 2022 Santa Fe Limited hesitating, lurching, and stalling (once) following acceleration from a complete stop, all without the Check Engine Light (CEL) illuminating (which the dealership said is needed to initiate troubleshooting). In addition, there is a common thread where dealerships are telling owners that it is "... probably bad gas." On 2 October 2023 the SUV started and was idling very rough, and as I drove off, the CEL illuminated (finally). After turning off the SUV for five minutes, it started fine with no CEL. My OBD-II code reader pulled three codes from the SUV that afternoon: P0300, P0301, and P0302 (Misfire - General, Misfire - Cylinder 1, and Misfire - Cylinder 2). The trouble codes should be sufficient for the service department to locate a problem, and to their credit I was placed in a loaner vehicle when I dropped the SUV off on 7 October 2023. So far (24 October), they have not identified a problem, even though there is a fuel injector Technical Service Bulletin (TSB) for multiple Hyundai vehicles (including my Make/Model/Year) that may or may not apply to my specific vehicle. Bottom line: The vehicle is unsafe to drive (as I told the service manager), has had this problem for approximately one year, and if the vehicle stalls when I am entering traffic it is not going to end well - not for me in a stalled vehicle and not for Hyundai after they had an opportunity to address the problem.
